Proposing a dual-port FeFET design to eliminate pass disturb in vertical NAND storage.
Streszczenie
The article introduces a dual-port FeFET design to address pass disturb in vertical NAND storage. It explains the challenges faced by single-port designs and the benefits of the proposed dual-port structure. The content covers the origin of pass disturb, experimental verifications, and integration into highly scaled vertical NAND arrays. Detailed insights are provided on the structural modifications, operational principles, and experimental validations of the dual-port FeFET design.
Statystyki
"The proposed design can be incorporated in a highly scaled vertical NAND FeFET string."
"A high VPASS could disturb the memory states."
"VPASS needs to be greater than the highest threshold voltage (VTH) to ensure turning ON unselected cells."
"A narrow VPASS margin is available and sometimes a tradeoff has to be made."
Cytaty
"The proposed design features an independent non-ferroelectric pass gate for the read and pass operation."
"We argue that there will be negligible disturb to the memory states with the dual-port transistor design."
